Love the odd-fire motor, but if it ever needed replacing I'd find a '79~'80 3.8L. Cheaper, and I'd have the option of fuel injection and just overall better parts availability.- EchoWars

As a followup, the shop told me that the spring seats in several locations were about 0.030" lower than the others and probably grenaded their measurements. Regardless, the end result was a range of stem heights that were going to be a problem. Solution? New exhaust valves, and grind them so...- EchoWars

#480 coming up for sale...
Cool though that may be, it's also sad. Cars are made to be driven. That one is yearning to stretch its legs.- EchoWars

I had considered this. AssUming ;) a 1.55 actual ratio (1.6 is the spec), the .034" delta ends up making a .020" difference in lifter preload. Too damn much.- EchoWars

Oops...guess I didn't read carefully enough. Still, looks like that '87 head wants longer valves than my '69. As I put in the first post: Kaiser Jeep FSM spec: 1.925" (I'm assuming that that is an absolute minimum usable length) 2006 AERA Engine Builders Association book: 1.930" to 1.970" (I'm...- EchoWars

The machined valve seat surface extends beyond the diameter of the retainer just enough to get the tail end of a caliper to make a reliable measurement from there to the top of a straight edge laid on top of the valve. Straight edge is .060" thick, so that is subtracted from my measurement to...- EchoWars

Does that sound like a measurement from valve tip to retainer? :giggle: (I'd love to see the engine that valve goes to) After I eyeballed the retainers and saw that there may have been an issue, that was the first thing I did. Sounds like someone wants numbers, so here they are: Valve Stem...- EchoWars

Rgr on the 'oal', I should have guessed. Yes, I know it's not the proper tool, but I'm not a machinist and it's not something I'd be likely to use again (re: spring compressor - seems to have sprouted legs and walked off, but I'm not about to start disassembling the machine shop work and then...- EchoWars

Digital caliper with a straight edge across the top of the stem. Thickness of my straight edge subtracted from my final reading. I do not claim that this is a super-accurate method for measuring stem height, but I'm confident that the difference I have measured from one stem to the next is...- EchoWars

Hi guys! Been reading here for a long time, and was actually surprised to see that, when I went to post, that I had not actually registered. Corrected. :p Forgive me, but I'm actually working on a 225 OF V6 out of a Jeep. Yes, the granddaddy to all the turbo engines. But, I can't think of any...- EchoWars
